Among the several parameters proposed by different authors in a number of papers, channel length and width, braiding and sinuosity indexes, and channel lateral shifting are proved to be the most effective ones for a quantitative analysis of river changes. However, the calculation of these parameters is time-consuming, tedious and error-prone, even where made in a GIS environment. This work describes four shell scripts that perform fast and automatic calculation of the morphometric parameters and draw curves showing the variation of the calculated parameters along the entire channel development. The scripts are based on commands of the GRASS GIS free and open source software and, as input, they require a simple vector map containing the essential features of a river channel, i.e. bankfull channel limits and longitudinal and lateral bars.展开更多

Using the oral life-story of a woman who lived through the Mao era as an example, the article explores the ways suku operates as a master script in people＇s narratives about their lives. It argues that the adoption of the model in a certain sense resulted in the de-narration of gendered experience, as well as the de-narration of life in the post-Mao era, it further demonstrates that the suku narrative model limited not only the representation of certain experiences but also the construction of gender subjectivity. Furthermore, in the post-Mao era, instead of being the master script, the suku model often has to negotiate with other scripts, being revised, extended, redirected, and in some cases, replaced. One of these encounters, between the suku model and a feminist script, will be examined. The article argues that such encounter has the potential to challenge the master script and to create narrative space for women to narrate their gendered experience, and to construct a self-defined, more adequately articulated gender subjectivity.展开更多
